IMPROVEMENT IN EGG-BEATERS.

Specification forming part of Letters Patent N0. 157,456, dated December8, 1874; application filed July 24,1874.

To all whom 'it may concern:

Be it known that I, DONALD D. MAcKAY, of Whitestone,-in the county ofQueens and State of New York, have invented a new and useful Improvementin Egg-Beaters; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, which forms a part of this specification.

My present invention relates to that class of egg-beaters which employtwo or more stirrers or beaters, arranged. to revolve in differentcircles, and in different directions, relatively to each other; and itconsists in the combination of one or more main beaters, one or moreauxiliary beaters, and a stationary encompassing-frame, whereby Iproducea very efficient implement, by which the eggs or other substancesto be mixed are successively and repeatedly dashed by the severalbeaters against the stationary frame, and thus Amore efi'ectually beatenor mixed.

In the accompanying drawing, Figure l is a side view of an egg-beatercontaining my present improvement. Fig. 2 is a longitudinal section ofthe same and Fig. 3 is a trailsverse section of the same, taken on theplane ofthe line x a, Fig. 2.

The mechanism which I have shown for rotating the main or central beateris substantially the same as that shown and described in United StatesLetters Patent. No. 85,460,

granted to me December 29, 1868, which I will very brieiiy describe.

A designates a tubular hand-piece, having caps a b fitted on its ends.Within this hand-piece there is a stationary nut, C, and above this nuta spiral spring, E, bearing at the upper end against the cap a, and atthe lower end againsta movable disk, D. B is a rotary spindle, providedWith a spiral rib or thread, c. This spindle passes into the handpieceA, and its spiral rib or thread c works through the stationary nut O,and abuts against the movable disk D. v

By depressing the hand-piece the nut O is caused to travel along thespiral c, and rotate the spindle in one direction, and on relieving thehandle from pressure the spring E causes the parts to resume theiroriginal position,

and rotate the spindle in the reverse direction. This mechanism I do notclaim in the present application. Y

The spindle B is provided at its lower end with a beater, (see Fig. 1,)consisting, in the present instance, of a Wire frame, Gr H, of greaterWidth at the lower end than at its upper end, the upper ends of thewires Gr H being fastened in a collar secured to the spindle B. The saidbeater G H is encompassed in a frame consisting ofa base, g, two sidepieces, e c, and a box, al d', through which frame the spindle B passes,it being stepped at its lower end into the base g of the frame, as shownat f. I I are-the auxiliary beaters. These are stepped at their lowerends in the said basepiece g ofthe frame, are journaled in the plate dof the box, and are provided at their upper ends with cog-Wheels J J,Which engage with a cog-Wheel secured on the spindle B.

From the foregoing it will be observed that the construction andrelative arrangement of the main beater Gr H and the a-uxiliary beatersI I is such that all the beaters are revolved in separate or distinctpaths, planes, or circles, (see arrows, Fig. 3;) that the ogee portionsof the beaters I I are thrown or revolved in substantially oppositedirections, and when doing so interlace with the main beater Gr Hwithout coming in contact with it or with each other; and that the saidseveral beaters G H and I and I successively and repeatedly dash themixture against the stationary side pieces c c of the frame d c c g.V

Hence a thorough and complete beating or stirring of the mass in whichthey are submerged takes place without the liability of creating an eddyof the Whole mass, and hence a very efficient and practical device forbeating eggs and other liquids is produced.

What I claim as my invention,`and desire to secure by Letters Patent,is-

The combination, with the beaters G H and I I', of the stationary framed c g, substantially as and for the purpose herein set forth.

DONALD D. MAOKAY.
